How can I change the speed of a particle set to PSYS_SRC_PATTERN_DROP?

[jak Scribe]

I have a script that creates a particle and targets it to a linked prim.

It works fine but its drops too slow.

I tried changing various particle settings but it makes no difference.

Which settings must be changed to decrease or increase the drop speed?

By definition the DROP mode doesn't give particles any speed or offset, so changing those won't make a difference. They will be affected by acceleration, wind, source position if that flag is enabled, and will start moving towards their target if those flags are enabled, though.

Assuming you mean to make the particles reach their target faster, turn down their max age: the target is reached in the particles' lifetime, no sooner, no later.

If you meant the particles are spawning too slow, then you'll need to adjust the burst rate.

Thats what I was afraid of hearing... Do you mean PART_MAX_AGE or SRC_MAX_AGE  ?

I wanted to try changing PSYS_SRC_ACCEL but not too sure how to do that.

Adjusting the PART_MAX_AGE, SRC_MAX_AGE, PART_START_SCALE and PART_END_SCALE helped.

 

Thanks Frionil 😀
